Letters Patent No. 94,796, dated September 14, 1869.

IMPROVEMENT IN LAMP-BURNERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Be it known that I, SYLVESTER W. WARREN, of

Boston, in the county of Suffolk, in the State of Masaccompanying drawings, and to the letters of refer ence marked thereon, of which- Figure 1 is a perspective view of the burner, with the chimney in position on the same.

Figure 2 is a top view of the burner, without the outer cone G.

Figure 3 is a top view of the bottom part of the burner, showing the wick-tube D, and shaft I, on which are fitted the'spur-Wheels H H, which are used for raising or lowering the wick.

Figure 4 is a top view of the outer cone G.

Figure 5 is a cross-section of fig. 3, showing the shape of the wick-tube D, and the manner in which it is attached to the bottom of the burner.

lily invention consists of a lamp-burner constructed of parts to be hereinafter more fully described.

1 form a support for the burner with a series of arms, A A; on the bottom of said support I out a thread, for attaching it to a lamp body, as shown by fig. 5, through the bottom of which I fit the wicktube D. I-then .make a cap, E, globular, in the bot tom of which. I fit the shaft I, on which are fitted two spur-wheels, H H. I then form a plate or base, of which fig. 2 is a top view, with the cone N. Across the bottom ofcone N, I fit a perforatedplate, 0, through the centre of which I make an opening the shape of tlie-wick-tube D, as shown in fig. 3, the object being to allow the burner to be placed on or taken oil, as may be desirable, in order to trim the wick.

The object of plate 0 is to prevent too sudden a rush of air to the flame below the cone N. It serves another purpose; it guides the wick-tube to the right position, relative to the opening in (zone N.

I now form a second cone, G, and fit it on overcone N, as shown in fig. 1, forming a chamber between the two cones, the object being to allow the air to pass up through the openings 0 0 0, as shown in figs. l and 2, so as to regulate the draught, and cause a perfect combustion.

It will be seen that chambers P and R are separate, connecting only above cone N.

I now make air-passages through this plate into the space enclosed by'chimncy L, as shown by the two arrows a: x, the object being to assist a draught inside the chimney.

I attach three arms, K K K, on the outer surface of the rest 1), so as to bear against the outer surface of the chimney L, to hold it in position on the base B.

Now, the operation is .as follows: When the wick is lighted, the heat from the flame comes in contact with the top of cone N, and it becomes, to some considerable extent, heated. This, of course, heats the air in the chamber R, at the top. The air thus being heated, a draught isreadily formed, which causes the air to pass readily through chamber B into the flame. The air thus passing through chamber R, serves to regulate the draught through chamber I, and allows the air there heated to feed just as fast as the flame requires it for combustion.

The flame, thus created, is bright "without flickering. The burner being made open at the botto'm, the air readily circulates around the wick-tube and base, below the chambers P and R. The heated air created in those chambers, P and R, causes the air to pass continually up through the base of the burner, thereby kceping it in a tolerably cool condition.

My wick-tube is circular'at the top, as shown by fig. 5, the object being to keep theavickthe same length, or nearly so, below the circle of the cone N, thereby preventing the edge of the flame from being thrown againstjthe chimney.

Having thus described the nature of my invention,

What I claim, and desire to secure by Letters Patout, is-- The combination,,lwith the two cones G N, of the check-plate 0, located at the base of the internalcone, to admit air into the chamber I, in connection with air-passages 0, for chamber R, skeleton frame A, and wick-tube D, when the parts are arranged andadapted to operate together, as described. 7
